Why Study Services?
Why Study Services? (1)
 Services dominate economy in most nations
 Understanding services offers you personal competitive
advantages
 Importance of service sector in economy is growing
rapidly:




Services account for more than 60 percent of GDP worldwide
Almost all economies have a substantial service sector
Most new employment is provided by services
Strongest growth area for marketing
Service Sector Contribution to Indian Economy
 In the Year 2010 the contribution of different sectors
was:
 Services: 58.4%
 Industry: 24.1%
 Agriculture: 17.5%
NAICS: A New Way to Classify and
Analyze the Service Economy
 NAICS—North American Industry Classification System—
now used to compile and record economic data by
national statistical agencies of the U.S., Canada, Mexico
 New classification system replaces old SIC (Standard
Industrial Classification) codes in U.S.
 Captures huge array of new service industries, each with
its own NAICS code
 NAPCS—North American Product Classification System—
assigns codes to thousands of service products
 Particularly useful for looking at rented goods services
 U.S. and Canadian data easily accessible on the Web;
information includes number of establishments and
employment
Some Newer Service Industries
Profiled by NAICS Codes But Not SIC
 Casino Hotels
 HMO Medical Centers
 Continuing Care Retirement
Communities
 Industrial Design Services
 Diagnostic Imaging Centers
 Investment Banking and
Securities Dealing
 Diet and Weight Reducing
Centers
 Management Consulting Services
 Environmental Consulting
 Satellite Telecommunications
 Golf Courses, Country Clubs
 Telemarketing Bureaus
 Hazardous Waste Collection
 Temporary Help Services
Why Study Services? (2)
 Most new jobs are generated by services
 Fastest growth expected in knowledge-based industries
 Significant training and educational qualifications required,
but employees will be more highly compensated
 Will service jobs lost to lower-cost countries? Yes, some service jobs
can be exported

What Are Services?
What Are Services? (1)

The historical view
 Goes back over 200 years to Adam Smith and Jean-Baptiste Say
 Different from goods because they are perishable (Smith 1776)
 Consumption cannot be separated from production, services are
intangible (Say 1803)

A fresh perspective: Services involve a form of rental,
offering benefits without transfer of ownership
 Include rental of goods
 Marketing tasks for services differ from those involved in selling
goods and transferring ownership
What Are Services? (2)

Five broad categories within non-ownership framework:
1.
2.
3.
4.
5.

Rented goods services
Defined space and place rentals
Labor and expertise rentals
Access to shared physical environments
Systems and networks: access and usage
Implications of renting versus owning (Service Perspectives 1.1)
 Markets exist for renting durable goods rather than selling them
 Renting portions of larger physical entity (e.g., office space, apartment) can
form basis for service
 Customers more closely engaged with service suppliers
 Time plays central role in most services
 Customer choice criteria may differ between rentals and outright purchases
 Services offer opportunities for resource sharing
Defining Services
 Services
 Are economic activities offered by one party to another
 Most commonly employ time-based performances to bring about
desired results in:
― recipients themselves
― objects or other assets for which purchasers have responsibility
 In exchange for their money, time, and effort, service
customers expect to obtain value from
 Access to goods, labor, facilities, environments, professional skills,
networks, and systems
 But they do not normally take ownership of any of the physical
elements involved
Service Products versus Customer Service
and After-Sales Service
 A firm’s market offerings are divided into core product
elements and supplementary service elements
 Is everyone in service? Need to distinguish between:
 Marketing of services
 Marketing goods through added-value service
 Good service increases the value of a core physical good
 After-sales service is as important as pre-sales service
for many physical goods
 Manufacturing firms are reformulating and enhancing
existing added-value services to market them as standalone core products
Challenges Posed by Services
Services Pose Distinctive
Marketing Challenges

Marketing management tasks in the service sector
differ from those in the manufacturing sector

The eight common differences are:
1.
2.
3.
4.
5.
6.
7.
8.

Most service products cannot be inventoried
Intangible elements usually dominate value creation
Services are often difficult to visualize and understand
Customers may be involved in co-production
People may be part of the service experience
Operational inputs and outputs tend to vary more widely
The time factor often assumes great importance
Distribution may take place through nonphysical channels

Expanded Marketing Mix
for Services
Services Require
An Expanded Marketing Mix
 Marketing can be viewed as:
 A strategic and competitive thrust pursued by top management
 A set of functional activities performed by line managers
 A customer-driven orientation for the entire organization
 Marketing is the only function to bring operating
revenues into a business; all other functions are cost
centers
 The “8Ps” of services marketing are needed to create
viable strategies for meeting customer needs profitably
in a competitive marketplace
The 8Ps of Services Marketing
 Product
 Place and Time
 Price and Other User Outlays
 Promotion and Education
 Process
 Physical Environment
 People
 Productivity and Quality
Fig 1.9 Working in
Unison: The 8Ps of
Services Marketing

(1) Product Elements
 Embrace all aspects of service performance that
create value
 Core product responds to customer’s primary need
 Array of supplementary service elements
 Help customer use core product effectively


Marketers must recognize that customer outlays
involve more than price paid to seller

Traditional pricing tasks:
 Selling price, discounts, premiums
 Margins for intermediaries (if any)
 Credit terms

Identify and minimize other costs incurred by users:
 Additional monetary costs associated with service usage (e.g.,
travel to service location, parking, phone, babysitting, etc.)
 Time expenditures, especially waiting
 Unwanted mental and physical effort
 Negative sensory experiences
The 8Ps of Services Marketing:
(4) Promotion and Education

 Content
 Information, advice
 Persuasive messages
 Customer education/training
The 8Ps of Services Marketing:
(5) Process
 How firm does things may be as important as what it does
 Customers often actively involved in processes, especially
when acting as co-producers of service
 Process involves choices of method and sequence in
service creation and delivery





Design of activity flows
Number and sequence of actions for customers
Nature of customer involvement
Role of contact personnel
Role of technology, degree of automation
 Badly designed processes waste time, create poor
experiences, and disappoint customers
The 8Ps of Services Marketing:
(6) Physical Environment

tangible evidence of service
performances
 Create and maintain physical
appearances




Improving Service Quality and Productivity
Overview of Session
 Integrating service quality and productivity strategies
 What is service quality?
 The Gaps Model—a conceptual tool to identify and
correct service quality problems
 Measuring and improving service quality
Integrating Service Quality and
Productivity Strategies
Integrating Service Quality and
Productivity Strategies
 Quality and productivity are twin paths to creating value
for both customers and companies
 Quality focuses on the benefits created for customers;
productivity addresses financial costs incurred by firm
 Importance of productivity:
 Keeps costs down to improve profits and/or reduce prices
 Enables firms to spend more on improving customer service and
supplementary services
 Secures firm’s future through increased spending on R&D
 May impact service experience—marketers must work to minimize
negative effects, promote positive effects
What Is Service Quality?
Different Perspectives of Service Quality
Transcendent:
Quality = Excellence. Recognized only through
experience
Product-based: Quality is precise and measurable
User-based:
Quality lies in the eyes of the beholder
Manufacturing- Quality is in conformance to the firm’s developed
based:
specifications
Value-based:
Quality is a trade-off between price and value
Components of Quality:
Service-based (SERVQUAL)
Tangibles: Appearance of physical elements
Reliability: Dependable and accurate performance
Responsiveness: Promptness; helpfulness
Assurance: Competence, courtesy, credibility,
security
Empathy: Easy access, good communication,
understanding of customer
Capturing the Customer’s Perspective of
Service Quality: SERVQUAL (1)
 Survey research instrument based on premise that
customers evaluate firm’s service quality by comparing
 Their perceptions of service actually received
 Their prior expectations of companies in a particular industry
 Poor quality
 Perceived performance ratings < expectations
 Good quality
 Perceived performance ratings > expectations
Capturing the Customer’s Perspective of
Service Quality: SERVQUAL (2)
 Developed primarily in context of face-to-face
encounters
 Scale contains 22 items reflecting five dimensions of
service quality
 Subsequent research has highlighted some limitations of
SERVQUAL
 See Research Insights 14.1: Measuring E-Service Quality
How Customers Might Evaluate Online
Businesses: Seven Dimensions of E-S-QUAL

Accessibility : Is site easily found?

Navigation: How easy is it to move around the site?

Design and presentation: Image projected from site?

Content and purpose: Substance and richness of site

Currency and accuracy


Responsiveness:Firm’s propensity to respond to e-mails
Interactivity, customization, and personalization

Reputation and security

Other Considerations in
Service Quality Measurement
 In uncompetitive markets or in situations where
customers do not have a free choice, researchers should
use needs or wants as comparison standards
 Time constraints
 Services high in credence characteristics may cause
consumers to use process factors and tangible cues as
proxies to evaluate quality—halo effect
 Process factors: Customers’ feelings

4. Internal communications gap: Ensure that
communications promises are realistic
 Seek comments from frontline employees and operations personnel
about proposed advertising campaigns
 Get sales staff to involve operations staff in meetings with
customers
 Ensure that communications sets realistic customer expectations
Prescriptions for Closing the
Seven Service Quality Gaps (3)
(Table 14.3)
5. Perceptions gap: Educate customers to see reality of
service quality delivered
 Keep customers informed during service delivery and debrief after
delivery
 Provide physical evidence
6. Interpretation gap: Pretest communications to make
sure message is clear and unambiguous
 Present communication materials to a sample of customers in
advance of publication
7. Service gap: Close gaps 1 to 6 to meet customer
expectations consistently
Measuring and Improving
Service Quality
Soft and Hard Measures
of Service Quality
 Soft measures—not easily observed, must be collected by
talking to customers, employees, or others
 Provide direction, guidance, and feedback to employees on ways to
achieve customer satisfaction
 Can be quantified by measuring customer perceptions and beliefs
―For example: SERVQUAL, surveys, and customer
advisory panels
 Hard measures—can be counted, timed, or measured
through audits
 Typically operational processes or outcomes
 Standards often set with reference to percentage of occasions on
which a particular measure is achieved
 Control charts are useful for displaying performance over time
against specific quality standards
Soft Measures of Service Quality
 Key customer-centric SQ measures include:




Total market surveys, annual surveys, transactional surveys
Service feedback cards
Mystery shopping
Analysis of unsolicited feedback—complaints and compliments, focus
group discussions, and service reviews
 Ongoing surveys of account holders to determine satisfaction in
terms of broader relationship issues
 Customer advisory panels offer feedback/advice on performance
 Employee surveys and panels to determine:
 Perceptions of the quality of service delivered to customers on
specific dimensions
 Barriers to better service
 Suggestions for improvement
Hard Measures of Service Quality
 Control charts to monitor a single variable
 Offer a simple method of displaying performance over time against
specific quality standards
 Are only good if data on which they are based is accurate
 Enable easy identification of trends
 Service quality indexes
 Embrace key activities that have an impact on customers

Tools to Analyze and Address
Service Quality Problems
 Fishbone diagram
 Cause-and-effect diagram to identify potential causes of problems
 Pareto Chart
 Separating the trivial from the important. Often, a majority of
problems is caused by a minority of causes (i.e. the 80/20 rule)
 Blueprinting
 Visualization of service delivery, identifying points where failures
are most likely to occur
Tools to Analyze and Address
Service Quality Problems (Appendix)
 Total Quality Management (TQM)
 ISO 9000
 Comprises requirements, definitions, guidelines, and related
standards to provide an independent assessment and certification of
a firm’s quality management system
 Malcolm Baldrige Model Applied to Services
 To promote best practices in quality management, and recognizing,
and publicizing quality achievements among U.S. firms
 Six Sigma
 Statistically, only 3.4 defects per million opportunities (1/294,000)
 Has evolved from defect-reduction approach to an overall businessimprovement approach
